This summary report is intended to provide answers to questions that local school personnel may have concerning the 1980-81 South Carolina Statewide Testing Program. The Comprehensive Tests of Basic Skills, Form S(CTBS/S), which measure reading, language, mathematics, science, social studies, and reference skills, were administered to 134,753 South Carolina students in grades 4, 7, and 10. The results for each subject area are presented for all students and Title I students. The major changes in the 1980-81 Statewide Testing Program was the move to testing at grades 4, 7, and 10 from grades 3, 6, and 11. This change established a new baseline year in terms of comparison of test data across years. 1980-81 data are not comparable with results from previous years due to this grade level testing change. Longitudinal comparisons may be made which compare the same students across the years from 1976-77 to 1980-81. (Author/PN)
